Construction Project Forecasting ＂Practical Use of EV Metrics＂

During this professional research--Construction Project Forecasting （Practical Use of EV Metrics）, which criticize earned value management as a most distinguished methodology for forecasting the project expected end dates and expecting budget at completion, the field for the research is construction field and specially the projects which content different phases without repetitive tasks. Forecasting for construction project is a complicated process need more than applying one equation only. As assuming that, project performance during finishing stage will be similar to project performance during concrete stage is totally wrong. The case study techniques have been used to prove an important idea and also to implement a suggested protocol which actually implemented and tested and it should be considered as a research finding. The project used in this case study is ＂Hurgadah Intemational Airport--New Terminal Building＂, while executing this complex construction projects with different stages the forecasting for the project end date and final end budget were completely not realistic. The above leads to questioning the next： ＂Is it true that using the earned value indexes for forecasting construction projects end date and final budget is the right way？ And if not, what is the right process that should be used in order to reach acceptable forecasting method？＂ We implement the EV measurements by the normal technique and also implement in the same month the suggested protocol for forecasting, comparing the results proof the effectiveness of the suggested protocol. The findings prove that, the construction projects need special treatment when use the EVM for forecasting. The earned value indexes created to serve the projects which have repeated tasks or can say which got one stage only, like information technology （IT） projects as those projects depending on manpower productivity and also based on few different qualifications. On such type of projects the earned value forecasting calculation is perfectly used.

Complete fuzzy scheduling and fuzzy earned value management in construction projects

This paper aims to present a comprehensive proposal for project scheduling and control by applying fuzzy earned value.It goes a step further than the existing literature:in the formulation of the fuzzy earned value we consider not only its duration,but also cost and production,and alternatives in the scheduling between the earliest and latest times.The mathematical model is implemented in a prototypical construction project with all the estimated values taken as fuzzy numbers.Our findings suggest that different possible schedules and the fuzzy arithmetic provide more objective results in uncertain environments than the traditional methodology.The proposed model allows for controlling the vagueness of the environment through the adjustment of the α-cut,adapting it to the specific circumstances of the project.

Construction engineering management culture shift: Is the lowest tender offer dead?

The procurement of public construction projects must walk a fine line between the corruption of state officials and collusion of contractors. The method of awarding projects to the lowest responsible tenderer was originally implemented to guard against corruption of state officials. However, an investigation of the construction industry in the Canadian province of Quebec showed that lowest-tender-offer procurement gave rise to collusion of companies tendering for the contracts. Alternatively, bestvalue procurement has been used for decades, but here problems arise owing to the necessity of subjective judging of measures other than price to compare bids, giving rise to time-and money-consuming protests. The paper proposes a compelling argument that the construction engineering management(CEM) culture should refocus its efforts on enhancing project cost certainty rather than merely searching for means to design a project in a manner that produces the lowest initial cost, and awards the construction to the lowest tender offer that focuses on cost savings during the project development and delivery process. The difference in the two approaches is subtle but extremely important. To make the transition, the engineering management tools must be advanced to the next level.This means that all project control tools for managing cost,schedule, and technical scope must be transformed from working in the deterministic mode to the stochastic mode,thus making the probability of completing the projectwithin or below its official budget the primary decision criterion. To do so, CEMs must accept that there is a benefit in paying more for an alternative that increases cost certainty for the entire project. The authors of this paper hope that it will provide the grist for a more general dialog across all industry sectors where engineering management is practiced.

Modeling the effect of a freeway road construction project on link-level travel times

Drivers experience variations in travel time due to congestion and delays associated with road construction projects on existing transportation facilities. The effect on the travel time of a link decreases as its distance from the road construction project increases. In addition, the effect could extend to the connecting arterial street links within the vicinity of the road construction project. Therefore, the focus of this research is to model the effect of a road construction project on the freeway and connecting arterial street link-level travel times. Data pertaining to a resurfacing construction project, which lasted for six months,was gathered from the traffic incident management systems(TIMS). The travel time data was collected and processed, for each selected freeway and connecting arterial street link,for six months before the start of the resurfacing construction project and six months during the construction of the resurfacing project. Generalized linear models(GLM) were developed and validated for before and during the construction project periods with the average travel time on a link as the dependent variable. Data such as time-of-the-day, dayof-the-week, the distance of a link from the work zone, subject link characteristics, and upstream and downstream link characteristics were collected and used as the predictor variables. The results indicate that the subject link, upstream link and downstream link characteristics have a significant effect on the freeway and connecting arterial street linklevel travel times due to the resurfacing construction project.
